Steps: 1.Using getosudatas.m to obtain training samples for the neural newtork 2.Train the network (Now I use the command 'nnstart' in matlab, which will genrate a function: MyNeuralNetworkFunction.m) 3.Choosing a song file, using NNmapping.m to generate a structure 'tp',which contains the information of beatmap. 4.Create an .osu file with tp and createOsuFile.m
